Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not
wearing the watch, leave it
in a location where it is
exposed to light.
• Best charging
performance is achieved
by exposing the watch to
the strongest light
available.
When wearing the watch,
make sure that its face is
not blocked from light by the
sleeve of your clothing.
• The watch may enter a
sleep state (page E-16) if its
face is blocked by your
sleeve even only partially.

• The flashing charge alert at Level 3 and the flashing charge alert (
C
) at Level
4 tell you that battery power is very low, and that exposure to bright light for
charging is required as soon as possible.
• At Level 5, all functions are disabled and settings return to their initial factory
defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the
current time, date, and other settings.
• The watch’s Home City code setting will change automatically to
TYO
(Tokyo)
whenever the battery drops to Level 5. If you are using the watch in North America
or Europe, or China you will need to change the Home City code setting to match
your location after the battery drops to Level 5.
• Display indicators reappear as soon as the battery is charged from Level 5 to Level
2.
• Leaving the watch exposed to direct sunlight or some other very strong light source
can cause the battery power indicator to show a reading temporarily that is higher
than the actual battery level. The correct battery level should be indicated after a
few minutes.

Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the conditions below for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
Important!
• Allowing the watch to become very hot can cause the digital display to black out.
The appearance of the LCD should become normal again when the watch returns
to a lower temperature.
• Enable the watch’s Power Saving function (page E-16) and keep it in an area normally
exposed to bright light when storing it for long periods. This helps to ensure that
power does not run down.
• Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause power to run down.
Expose the watch to bright light whenever possible.

watch to lose or gain time, to stop, or otherwise malfunction.
x Leaving your watch in an area hotter than +60°C (140°F) for long periods can lead
to problems with its LCD. The LCD may become difficult to read at temperatures
lower than 0°C (32°F) and greater than +40°C (104°F).
Impact
x Your watch is designed to withstand impact incurred during normal daily use and
during light activity such as playing catch, tennis, etc. Dropping your watch or
otherwise subjecting it to strong impact, however, can lead to malfunction. Note that
watches with shock-resistant designs (G-SHOCK, BABY-G, G-MS) can be worn
while operating a chain saw or engaging in other activities that generate strong
vibration, or while engaging in strenuous sports activities (motocross, etc.)
E-58
Band
x Tightening the band too tightly can cause you to sweat and make it difficult for air
to pass under the band, which can lead to skin irritation. Do not fasten the band too
tightly. There should be enough room between the band and your wrist so you can
insert your finger.
x Deterioration, rust, and other conditions can cause the band to break or come off
of your watch, which in turn can cause band pins to fly out of position or to fall out.
This creates the risk of your watch falling from your wrist and becoming lost, and
also creates the risk of personal injury. Always take good care of your band and
keep it clean.
x Immediately stop using a band if you even notice any of the following: loss of band
flexibility, band cracks, band discoloration, band looseness, band connecting pin
flying or falling out, or any other abnormality. Take your watch to your original
retailer or to a CASIO service center for inspection and repair (for which you will be
charged) or to have the band replaced (for which you will be charged).
E-57
x A trained technician will inspect your watch for proper water resistance whenever
you have its battery replaced. Battery replacement requires the use of special tools.
Always request battery replacement from your original retailer or from an authorized
CASIO service center.
x Some water-resistant watches come with fashionable leather bands. Avoid
swimming, washing, or any other activity that causes direct exposure of a leather
band to water.
x The inside surface of the watch glass may fog when the watch is exposed to
a sudden drop in temperature. No problem is indicated if the fogging clears up
relatively quickly. Sudden and extreme temperature changes (such as coming into
an air conditioned room in the summer and standing close to an air conditioner
outlet, or leaving a heated room in the winter and allowing your watch to come into
contact with snow) can cause it to take longer for glass fogging to clear up. If glass
fogging does not clear up or if you notice moisture inside of the glass, immediately
stop using your watch and take it to your original retailer or to an authorized CASIO
service center.
x Your water-resistant watch has been tested in accordance with International
Organization for Standardization regulations.
E-56
x Watches that do not have WATER RESIST or WATER RESISTANT marked on the
back cover are not protected against the effects of sweat. Avoid using such a watch
under conditions where it will be exposed to large amounts of sweat or moisture, or
to direct splashing with water.
x Even if a watch is water resistant, note the usage precautions described below.
Such types of use reduce water resistance performance and can cause fogging of
the glass.
− Do not operate the crown or buttons while your watch is submersed in water or
wet.
− Avoid wearing your watch while in the bath.
− Do not wear your watch while in a heated swimming pool, sauna, or any other high
temperature/high humidity environment.
− Do not wear your watch while washing your hands or face, while doing housework,
or while performing any other task that involves soaps or detergents.
x After submersion in seawater, use plain water to rinse all salt and dirt from your
watch.
x To maintain water resistance, have the gaskets of your watch replaced periodically
(about once every two or three years).

Note
• Performing repeated signal receive, alarm, hourly time signal, light, or other similar
operations over a short time can cause a sudden drop in watch’s charge. When this
happens, the watch enters the Recover Mode, indicated by
R
(Recover) flashing on
the display. The Recover Mode is the same as a low battery charge state.
• Access to some functions is limited while the watch is in the Recover Mode. Normal
operation will resume after recovery is complete. For more information, see
“Recover Mode” (page E-14).
• A flashing
R
(Recover) or
C
indicator means that the charge level of the watch is
extremely low. Immediately expose the watch to light to charge it.
E-51
World Time Mode
■
The time for my World Time City is not correct in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving
time. See “To specify standard time or daylight saving time (DST) for a city” (page E-32)
for more information.
Charging
■
The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 5 (page E-12). Continue exposing
the watch to light until the battery power indicator shows HI or MID.
■
Flashing R Indicator
The watch is in the Recover Mode. Wait until recovery is complete (about 15 minutes).
The watch will recover more quickly if you place it in a brightly lit location.

■
The current time setting is off by hours.
Your Home City setting may be wrong (page E-24). Check your Home City setting and
correct it, if necessary.
■
The current time setting is off by one hour.
You may need to change your Home City’s standard time/daylight saving time (DST)
setting. Use the procedure under “To change the current time and date settings” (page
E-27) to change the standard time/daylight saving time (DST) setting.
■
The hands are misaligned.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand alignment. Adjust the watch’s hand
home position alignment (page E-45).
Operation Guide 5576
E-69
Battery
x The special rechargeable battery used by your watch is not intended to be removed
or replaced by you. Use of a rechargeable battery other than the special one
specified for your watch can damage your watch.
x The rechargeable (secondary) battery is charged when the solar panel is exposed
to light, so it does not require regular replacement as the primary battery requires.
Note, however, that long use or operating conditions can cause the capacity or
charging efficiency of the rechargeable battery to deteriorate. If you feel that the
amount of operation provided by charging is too short, contact your original retailer
or CASIO service center.
E-68
x Even if the surface of the metal appears clean, sweat and rust in crevasses can
soil the sleeves of clothing, cause skin irritation, and even interfere with watch
performance.
Premature Wear
x Leaving sweat or water on a resin band or bezel, or storing your watch an area
subject to high moisture can lead to premature wear, cuts, and breaks.
Skin Irritation
x Individuals with sensitive skin or in poor physical condition may experience skin
irritation when wearing a watch. Such individuals should keep their leather band
or resin band particularly clean. Should you ever experience a rash or other skin
irritation, immediately remove your watch and contact a skin care professional.
E-67
x Clean water and sweat from a leather band by wiping with a soft cloth.
x Not operating a watch crown, buttons, or rotary bezel could lead to later problems
with their operation. Periodically rotate the crown and rotary bezel, and press
buttons to maintain proper operation.
Dangers of Poor Watch Care
Rust
x Though the metal steel used for your watch is highly rust-resistant, rust can form if
your watch is not cleaned after it becomes dirty.
− Dirt on your watch can make it impossible for oxygen to come into contact with the
metal, which can lead to breakdown of the oxidization layer on the metal surface
and the formation of rust.
x Rust can cause sharp areas on metal components and can cause band pins to fly
out of position or to fall out. If you ever notice any abnormality immediately stop
using your watch and take it to your original retailer or to an authorized CASIO
service center.
E-66
User Maintenance
Caring for Your Watch
Remember that you wear your watch next to your skin, just like a piece of clothing.
To ensure your watch performs at the level for which it is designed, keep it clean by
frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat,
water and other foreign matter.
x Whenever your watch is exposed to sea water or mud, rinse it off with clean fresh
water.
x For a metal band or a resin band with metal parts, use a soft toothbrush or similar
tool to scrub the band with a weak solution of water and a mild neutral detergent, or
with soapy water. Next, rinse with water to remove all remaining detergent and then
wipe dry with a soft absorbent cloth. When washing the band, wrap the watch case
with kitchen plastic wrap so it does not come into contact with the detergent or soap.
x For a resin band, wash with water and then wipe dry with a soft cloth. Note that
sometimes a smudge like pattern may appear on the surface of a resin band. This
will not have any effect on your skin or clothing. Wipe with a cloth to remove the
smudge pattern.
E-65
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any
damage or loss suffered by you or any third party arising through the use of your
watch or its malfunction.
E-64
x Use a soft toothbrush or similar tool to scrub the metal with a weak solution of water
and a mild neutral detergent, or with soapy water. Next, rinse with water to remove
all remaining detergent and then wipe dry with a soft absorbent cloth. When washing
metal components, wrap the watch case with kitchen plastic wrap so it does not
come into contact with the detergent or soap.
Bacteria and Odor Resistant Band
x The bacteria and odor resistant band protects against odor generated by the
formation of bacteria from sweat, which ensures comfort and hygiene. In order
to ensure maximum bacteria and odor resistance, keep the band clean. Use an
absorbent soft cloth to thoroughly wipe the band clean of dirt, sweat, and moisture.
A bacteria and odor resistant band suppresses the formation of organisms and
bacteria. It does not protect against rash due to allergic reaction, etc.
Liquid Crystal Display
x Display figures may be difficult to read when viewed from an angle.
E-63
Leather Band
x Allowing your watch to remain in contact with other items or storing it together with
other items for long periods while it is wet can cause the color of the leather band
to transfer to the other items or the color of the other items to transfer to the leather
band. Be sure to dry off your watch thoroughly with a soft cloth before storing it and
make sure it is not in contact with other items.
x Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for
long periods or failure to clean dirt from a leather band for long periods can cause it
to become discolored.
CAUTION: Exposing a leather band to rubbing or dirt can cause color transfer and
discoloration.
Metal Components
x Failure to clean dirt from metal components can lead to formation of rust, even if
components are stainless steel or plated. If metal components exposed to sweat
or water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a
well-ventilated location to dry.
E-62
x Leaving your watch where it is exposed to direct sunlight (ultraviolet rays) for long
periods or failure to clean dirt from your watch for long periods can cause it to
become discolored.
x Friction caused by certain conditions (strong external force, sustained rubbing,
impact, etc.) can cause discoloration of painted components.
x If there are printed figures on the band, strong rubbing of the printed area can cause
discoloration.
x Leaving your watch wet for long periods can cause fluorescent color to fade. Wipe
the watch dry as soon as possible after it becomes wet.
x Semi-transparent resin parts can become discolored due to sweat and dirt, and if
exposed to high temperatures and humidity for long periods.
x Daily use and long-term storage of your watch can lead to deterioration, breaking,
or bending of resin components. The extent of such damage depends on usage
conditions and storage conditions.
E-61
Chemicals
x Do not allow your watch to come into contact with thinner, gasoline, solvents, oils,
or fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain
such ingredients. Doing so can cause discoloration of or damage to the resin case,
resin band, leather, and other parts.
Storage
x If you do not plan to use your watch for a long time, thoroughly wipe it free of all dirt,
sweat, and moisture, and store it in a cool, dry place.
Resin Components
x Allowing your watch to remain in contact with other items or storing it together with
other items for long periods while it is wet can cause color on resin components
to transfer to the other items, or the color of the other items to transfer to the resin
components of your watch. Be sure to dry off your watch thoroughly before storing it
and make sure it is not in contact with other items.
E-60
Magnetism
x The hands of analog and combination (analog-digital) watches are moved by a
motor that uses magnetic force. When such a watch is close to a device (audio
speakers, magnetic necklace, cell phone, etc.) that emits strong magnetism, the
magnetism can cause timekeeping to slow down, speed up, or stop, resulting in the
incorrect time being displayed.
x Very strong magnetism (from medical equipment, etc.) should be avoided because it
can cause malfunction of your watch and damage to electronic components.
Electrostatic Charge
x Exposure to very strong electrostatic charge can cause your watch to display
the wrong time. Very strong electrostatic charge even can damage electronic
components.
x Electrostatic charge can cause the display to go blank momentarily or cause a
rainbow effect on the display.
